Static Electricity


I know that this is a lame picture but it was the only thing physics related on my computer. This is a picture of carpet. As we learned in class static electricity can be generated from shuffling our feet across it with socks on. When we shuffle our feet we are charging by friction. In charging by friction, when two materials rub against each other one of the materials will want electrons more than the other. In the case of our feet and the carpet, the carpet wants electrons more than our feet and so we become positively charged. After we are charged and we touch something like a doorknob or someone else sometimes we get shocked. This is due to a want for our bodies to become neutral again so some electrons from the doorknob or person flows to us resulting in a shock and affter we get shocked we become neutral again.
